Putting “Science” to “Art”
Mental Models
Basic Tools
Basic Rules
Practice
proportions, elements
line work, simple shapes
perspective, lighting
Sketch a bike (from the side)
drive chain?supporting weight?
frame connections? pedal attachment?
what is unknown? what is missing? does this seem right?
Sketch a bike (mental model)
The Basics Toolslines, circles, ellipse
35 degree ellipse
Uncertainty is Visible
Perspective
1 Point 2 Point 3 Point
The Basics Tools
The Horizon or Eye LineVertical Lines are always vertical
Proportions
note: no strong convergence of lines
The CubeClose Vanishing Points = High Distortion
lines that are parallel on the objet will converge
to the same VP
The Cylinder Horizon
minor axis
First Assignmentline sketches of dice
submit only 1 page of sketches (8.5x11) but should have many iterations beforehand3-5 dice, at least 2” in sizetry wide vanishing points to reduce distortionsame horizon for all dice various orientationsclean line work, no tracing (from memory)don’t fill in the dots, show your line workOK if dice have only one dot on each faceno pencilpractice your basic warm up 10 min/day
